Disarming the mustard oil bomb
TLDR
Sulfatase activity of this enzyme largely prevents the formation of toxic hydrolysis products arising from this plant defense system, thus enabling diamondback moths to use a broad range of cruciferous host plants. Expand
Butterfly genome reveals promiscuous exchange of mimicry adaptations among species
TLDR
It is inferred that closely related Heliconius species exchange protective colour-pattern genes promiscuously, implying that hybridization has an important role in adaptive radiation. Expand
Successful herbivore attack due to metabolic diversion of a plant chemical defense.
TLDR
Evidence is presented that larvae of the specialist insect, Pieris rapae (cabbage white butterfly, Lepidoptera: Pieridae), are biochemically adapted to the glucosinolate-myrosinase system, the major chemical defense of their host plants. Expand
The genetic basis of a plant–insect coevolutionary key innovation
TLDR
Mechanistic understanding in its proper historical context documents more ancient and dynamic plant–insect interactions than previously envisioned, and provides the tools for detailed molecular studies of coevolution from both the plant and insect perspectives. Expand
An ABC Transporter Mutation Is Correlated with Insect Resistance to Bacillus thuringiensis Cry1Ac Toxin
TLDR
It is suggested that ABC proteins may play a key role in the mode of action of Bt toxins and that ABC protein mutations can confer high levels of resistance that could threaten the continued utilization of BT–expressing crops. Expand
Evolution of insect olfactory receptors
TLDR
The olfactory system of the primary wingless bristletail Lepismachilis y-signata, the firebrat Thermobia domestica and the neopteran leaf insect Phyllium siccifolium is investigated, suggesting that ORs arose as an adaptation to a terrestrial lifestyle, but evolved later in insect evolution, with Orco being present before the appearance of ORs.

Paleopolyploidy in the Brassicales: Analyses of the Cleome Transcriptome Elucidate the History of Genome Duplications in Arabidopsis and Other Brassicales
TLDR
These findings contribute to the understanding of the dynamics of genome duplication and evolution within one of the most comprehensively surveyed clades of plants, the Rosids, and clarify the complex history of the At-α, At-β, and At-γ duplications of Arabidopsis. Expand
Antennal transcriptome of Manduca sexta
TLDR
The use of transcriptomic and microarray data is presented to identify members of the main olfactory gene families of Manduca sexta and compares the expression of the near-complete transcript sets in male and female antennae. Expand
A comprehensive transcriptome and immune-gene repertoire of the lepidopteran model host Galleria mellonella
TLDR
The generated data provide for the first time access to the genetic architecture of immunity in this model host, allowing us to elucidate the molecular mechanisms underlying pathogen and parasite response and detailed analyses of both its immune responses against human pathogens, and its coevolution with entomopathogens. Expand
Molecular traces of alternative social organization in a termite genome.
TLDR
The genome and stage-specific transcriptomes of the dampwood termite Zootermopsis nevadensis (Blattodea) are sequence and similarities in the number and expression of genes related to caste determination mechanisms support a hypothesized epigenetic regulation of caste differentiation. Expand
